Area Forecast Discussion National Weather Service New York NY 353 AM EDT Tue Apr 29 2025

SYNOPSIS
A cold front approaches from the west today and passes through late tonight into early Wednesday morning. High pressure then returns for much of Wednesday and Thursday. A warm front approaches Thursday night and lifts through the region on Friday, with an attendant cold front following during Saturday. Thereafter, high pressure attempts to build in from the west into early next week.

NEAR TERM /THROUGH TONIGHT/
SW-S winds for today with high pressure centered off the Mid- Atlantic coast. With mostly sunny conditions and mixing up to 900- 850mb for western portions of the forecast area unaffected by an onshore flow, went a few degrees above deterministic NBM, which has been consistently below its 25th percentile for the past several runs. Highs ranging from the low-mid 80s in the urban corridor of NE NJ to the upper 60s for the south-facing shores of LI and SE CT.

Given the deep mixing expected through the day for the warmest areas, dew points are expected to remain mostly 40-45 despite a persistent SW flow. This deeper mixing and warm temperatures will cause RH values to drop to 25-35% this afternoon. This dry air combined with wind gusts 25-30 mph may allow for the elevated risk of fire spread. As such, a collaborated SPS for Northeast NJ, the Lower Hudson Valley and CT is posted to address this potential this afternoon into early evening.

Weakening convection ahead of an approaching cold front brings chances (20-40%) of residual showers pushing into the forecast area tonight. A rumble of thunder still cannot be ruled out over the Lower Hudson Valley and vicinity during the earlier evening hours.
Any convection that survives will likely be below severe thresholds.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/
The cold front is expected to be in the vicinity of eastern LI at sunrise Wednesday. Building surface high pressure follows through the day and remains in control through Thursday as ridging continues aloft. Dry weather through at least Thursday afternoon. For highs on Wednesday, went closer to the warmer 50th percentile NBM given the progged temps at the top of the mixed layer and a NW flow.
Deterministic NBM looked good for Thursday with an onshore flow and more clouds around vs Weds.

Surface low pressure shifts NE through the eastern Great Lakes Region during Thursday night. A leading warm front is progged to reach part of the forecast area by daybreak Friday. Increased moisture with 850mb theta-e advection and isentropic lift bring chances (40-50%) of light rain or showers mainly after midnight.
Can't rule out an isolated rumble of thunder with some elevated instability, but it appears that any rainfall will more likely be relatively on the lighter side as guidance has consistently shown modest qpf totals for several days now.

LONG TERM /FRIDAY THROUGH MONDAY/
Digging trough into the Great Lakes region with a couple embedded shortwaves sends a frontal system toward the region late this week.
Associated warm front lifts thru locally Friday morning, with scattered showers possible to start before drying for the bulk of the afternoon. Attendant cold front then approaches late in the day, instigating another round of showers and perhaps tstorms as well ahead of the boundary Friday evening and night. Guidance is also converging on a frontal wave of low pressure developing along the boundary as it moves east, producing additional wet weather Saturday. The probability for severe weather is low. QPF outside any convective maxima thru this time should largely remain under an inch, though the slower progression of the entire system could enhance totals just a bit further.

Considerable uncertainty in the forecast moving into early next week, hinging on whether the associated upper low is able to sufficiently pass east, or cut off from the flow and meander nearby for several days. EPS and GEPS lean toward a cutoff solution, leading to a much more dreary outlook. Meanwhile, the bulk of 00Z GEFS members keep the system moving east, with high pressure quickly building in behind it early next week. Associated Pac energy remains offshore, and better sampling should help resolve the solution over the next day or two as it comes ashore.

The region lies in the warm sector of the system on Friday and sets up the mildest day of the period. Temperatures away from maritime influence, generally west of the Hudson River, likely climb into the upper 70s and lower 80s, with potential for mid 80s. Cooler along the immediate coast with onshore southerly flow, closer to 70. The region should fall back to more typical conditions behind the system early next week as high pressure attempts to return, though temperatures could be cooler should a meandering upper low remain nearby.

AVIATION /08Z TUESDAY THROUGH SATURDAY/
High pressure remains centered offshore today ahead of an approaching cold front. The front moves through early Wednesday.

VFR thru the day.

General S/SW flow today, speeds increase after 12Z with gusts 20 to 25 kt developing, and a sea breeze likely contributing a few additional knots to coastal terminals into the afternoon. Gusts persist this evening and into overnight, and an approaching cold front introduces the chance for a few rain showers, mainly north and west of NYC terminals after 3Z. Conditions dry behind the front, with flow veering NW into mid Wed AM.

MARINE
South to SW winds increase today with SCA conditions developing on all waters this afternoon. A cold front then passes through late tonight into Wednesday morning with gusts still above 25 kt and elevated seas on the ocean. SCA has been extended to parts of Wednesday on the ocean. Only other adjustment to the SCA was to extend it through the entire night for most of the non-ocean waters.
A period of sub-advisory conditions then follows for all waters for much of Weds afternoon through Thursday night as a high pressure ridge shifts through the region.

Strengthening southerly flow associated with an approaching frontal system could introduce a period of SCA conditions on the ocean beginning Friday, with wind gusts up to 25 kt and seas 5 to 6 ft.
Winds lighten Friday night, but elevated seas may linger into the weekend.

FIRE WEATHER
Dry conditions with the combination of low relative humidity values between mostly 25 and 35 percent and frequent wind gusts of 25 to 30 mph will create an elevated risk for fire spread this afternoon into early evening. Special Weather statements are out for portions of the area.

HYDROLOGY
There are no hydrologic concerns through the forecast period.

TIDES/COASTAL FLOODING
Astronomically high tides will couple with a modest S/SW flow to allow water levels to approach or just exceed minor flood thresholds in the more vulnerable locales of coastal Nassau, Queens, and Fairfield during this evening's high tide cycle.
